Updating vector elements in Rust

The entries of vectors are mutable and can be changed freely, using indices and the bracket notation, just like we do with static arrays:

let mut names = vec!["Andy", "Mary", "Cody"];

names[0] = "Mircea";
names[2] = "Mike";

// names is now ["Mircea", "Mary", "Mike"]
